coagulation and flocculation ppt

coagulation, the coagulant chemicals neutralize the electrical charges of the fine particles in the water, allowing the particles to come closer together and form large clumps. 1. FLOCCULATION Depends on: choice of additive, dosage, and conditions for floc formation. Flocculation: The process of agglomeration of the destabilized particles to such a size that separation by sedimentation and filtration is possible.
